PHONOGRAPH LIGHTING SYSTEM.

Specification of Letters Patent.

Patented Dec. 2%, 1921]..

To 1135 whom it may concern:

Be it known that 1, Ross M. G. Pnrnmrs, a citizen of the United States,residing in the city and county of New Haven, State of Connecticut, haveinvented a new and useful improvement in Phonograph Ligh"- ing Systems,of which the following is a specification.

The object oi my invention is to provide a lighting system which lightsthe space where the record is placed to operate the phonograph and alsothe-space in which the records are stored.

A further object of my invention is to provide a lighting system whichautomatically lights the space where the record is placed "for operationoi the phonograph upon the opening oi tne door or cover of that spaceand without'manual operation.

A further object of my invention is to provide a lighting system whichoperates to light the space in which the records are stored or kept bymanual operation of the lighting system whenit is desired to remove orreplace records from their places therein.

A still "further object oi my invention is to provide a lighting systemwhich automatically operates to shut off the light in both the spacewhere the record is placed to operate the phonograph and the light inthe space where records are stored upon the closing of the door or coverof the phonograph.

Still further objects ofmy invention will be apparent from the followingdetailed description and the accompanying drawings which showembodiments of my invention and. in which similar reference charactersrefer to similar parts.

Figure l. is a side view in cross section of the upper part of aphonograph showing the arrangement of my lighting system therein.

Fig. is a similar viewto Fig. l. but thetop or cover of the phonographis shown in raised or open position and the connec tions and switchesare in the position in which my lighting system lights both the space inwhich records are placed to operate the phonograph and the space inwhich records are stored.

Fig. ill. 18 a front view of the upper part of a phonograph showing thearrangement of my lighting system therein with a front view in crosssection of the automatic means for turning the lights on and oil'.

Fig IV. is a side view oi the automatic switch used in my lightingsystem.

Fig. V. is a section of Fig. IV. on the lines i i-A.

Fig. Vi. isa view of the light used to light the space where the recordis placed to operate the phonograph, the bulb being removed and theposition and arrangement of the reflector is also shown.

Fig. VII. shows a diiierent form 01? reflector which entirely surroundsthe lamp and is adjustably mounted to throw the light to differentparts, as required.

F VH1. shows the position of lever 12 when switch 9 is closed and switch10 is open.

An electric cord 1 is attached to a source of electric current andenters through an opening l: the phonograph cabinet 2 which has a cover3 and space for storage of records l. The cord 1 is connected to theposts 5 and 6 in theswitchboard 7 which is comprised ofany insulatingmaterial andis attached to the interior or. the cabinet 53-.

he post 5 is electrically connectedto the bar 8 which iselectricallyconnected to the lrnite blade switches 9 and 10. lrlountedon the knife blade switch 9 is the shoulder 11 which is made ofinsulating material, such as fiber, asbestos or other suitable materialwhich carries the lever 12 extending above the cabinet 2 to the stop 13of the cover 3. in lever 19 is rnoveahly mounted the link 1% which ismade of insulating material such as fiber. asbestos or other suitablematerial which is connected to lrniie hlade switch 10. connected to post15 and connection plate 16. Posts 6 and 15 are connected by wire 1'?shown in dotted lines in IV. This wire is laid in a hollow groove in thesides of switchhoarr l. Electric cord 19 is electrically connected topesto and and contact plate 2'20. Cord 18 is'connected by orijlinaryelectric means to larip 21 which has a reflector- 22. Lamp 2-1 ispreferably mounted in the tor-ward part of cover and reflector israngedto throw the light toward sound Electric cord 1811selectricallybox 45. Cord 19 is connected to lamp 23 in the space forstoring records. Lamp 23 is preferably mounted in the upperpa-rt 0 space4.

Lever 12 has a notch 24 adapted to engage the pin 25 and is connected at26 to tension spring 27, which is fixed at 28 by a nut or bolt.

Lever 12 may be placed in any of the three positions shown in Fig. IV.If lever 12 is in position C, there is no connection between knife bladeswitches 9 and 10 and contact plates 16 and 20. Lever 12 is held in thisposition by pin 25 in notch 24. Lever 12 is placed in this position whenthe lighting system is not used.

If lever 12 is placed in position D, tension spring 27 tends to draw itupward and thus make a connection between knife blade switch 9 andcontact plate 16. Stop 13 in cover 3 prevents this when cover 3 is downbut when the cover is lifted, spring 27 causes this connection to bemade. No contact will be made between knife blade switch 10 and contactplate 20 because the link 14 is made short so as to prevent this.

If lever 12 is in position E, contact is made between knife bladeswitches 9 and 10 and contact plates 16 and 20 respectively. (See Fig.II.)

The current from a source of supply (not shown) flows through cord 1 topost 5 thence to knife blade switches 9 and 10. Knife blade switch 9 isin contact with plate 16. See Fig. VIII. In Fig. IV. the D position oflever 12 presumes lid 3 is closed down. If lid 3 is raised position D ismodilield by slight movementof lever 12 to the right of position D asshown the current flows to light 21' and a return is made through posts15, wire 17, post 6 and cord 1.

If contact is made by knife blade switch 10 lever 12 in position E Fig.IV,) with contact plate 20, the current flows through cord 19 to light23 and returns through cord 19, which in my preferred form is a twowirecord, post 6 and cord 1. V

lVhen the cover of the phonograph is closed, stop 13 presses lever 12down (Fig. I.) and breaks the connection between knife blade switch 9and contact plate 16. When cover 3 is raised spring 27 draws lever 12upward and makes a connection between knife blade switch 9 and contactplate 16 and lamp 21 is lighted. If it is desired to light lamp 23 inthe record storage space 4, lever 12 is manually drawn forward to makethe connection between knife blade switch 10 and contact plate 20, whichresults in lamp 23 being lighted. Contact plate 20 is arranged tocontact tightly with knife blade switch 10 and the friction created bythe contact is sufficient to overcome the pressure of spring 27Sufficient friction between these parts may be created by mounting part20 closely to part 7 but with sufiicient free dom to receive knife bladeswitch 10 under pressure or by any of the other means in the art. Whenthe cover 3 is closed stop 13 presses down lever 12 and thus breaks thecontact between knife blade switch 9 and contact plate 16 and knifeblade switch 10 and contact plate 20. Stop 13 is positioned to operateon lever 12 in either the position shown in Fig. II. or in Fig. VIII.

In the construction shown in my preferred form,- bar 8 is fastened toplate 7, parts 9 and 14 function as links to support lever 12. Part 9 isfastened to part 11 which is pivoted to the lower end of lever 12. Oneend of part 9 is pivoted to bar 8. One end of part 14 is pivoted tolever 12and the other to knife switch 10. The distance between thepivots of part 14 is shorter than the distance between the pivots ofparts 9 and 11 and a line connecting the pivots of parts 9 and 11 has agreater slope than the line connecting the pivots of part 14. Lever 12is, in effect, supported by the two links parts 9 and 14. The lower endof lever 12 moves to the left (Fig. IV.) as it is raised by spring 27Spring 27 maintains the lever 12 against stop 25 and therefore lever 12is tilted to the right when lever 12 is released by raising cover 3.With the proportion of the parts as shown considerable movement of lever12 upwardly is required to close switch 16. Due to the tension of spring27 the D position of lever 12 (FigsI. and IV.) is an unstable positionand the lever must be held in this position and this is done by stop 13in cover 3. The E position of lever 12 is further shown in Fig. II.

In the embodiment shown in Fig. VII. lamp 21 has the cylinder reflector22 mounted in a support 29 which is attached by the hinge 30 to theplate 31 which is secured in the wall of the phonograph. This permitsadjustment of the light to different parts of the space in which therecord is placed to operate the phonograph.

By my lighting system, when the cover or door of the phonograph isopened for the purpose of operating the same, a supply of light issecured by the opening of the door or cover. This gives light 'toplacerecords upon the turntable, locate needles, place needles in the soundbox and adjust the needle upon the record. If a record is to be selectedfrom the record cabinet or space where records are stored, a supply oflight may be secured in that place by moving the lever 12 forward.Meantime the supply of light in the upper part of the cabinet will becontinued. When necessary steps to select a record'and place same inoperating position have been completed the supply of light in both theupper space and in the a record cabinet are automatically cut off by theclosing of the top of the phonograph.
